Closely coupled evolutionary history of ecto- and endosymbionts from two distantly related animal phyla.

abstract：:Domestic species such as cattle (Bos taurus taurus and B. t. indicus) represent attractive biological models to characterize the genetic basis of short-term evolutionary response to climate pressure induced by their post-domestication history. Here, using newly generated dense SNP genotyping data, we assessed the stru...
